These mounting instructions are intended for specialists, who are quali-
fied to erect lightning protection systems, e.g. lightning protection spe-
cialists. These specialists must know the lightning protection standards
applicable at the mounting location, as well as the generally recognised
rules of technology.
1.2 Using these instructions
• These instructions are based on the standards valid at the time of
compilation (January 2018).
• Before commencing work, read these instructions through once com-
pletely. In particular, please observe the safety instructions.
• Keep all the documents supplied with the isCon® system safe, so that
the information is available should you need it.
• We will not accept any warranty claims for damage caused through
non-observance of these instructions.
• Regional and seasonal factors were not taken into account.
• To find out more about planning and installation using the OBO isCon®
system, we recommend a comprehensive training course.

About these instructions
1.4 Correct use
The OBO isCon® system is a lightning protection system for the external
lightning protection of buildings and systems, which, in the case of direct
lightning strikes, can arrest the lightning surge currents into the earth,
thus protecting the building, the system and people against the impacts of
the lightning strike, e.g. fires, mechanical building damage and possibly
lethal voltages and current pulses.
The system is not designed for any other purpose than the one described
here. If the system is installed and used for another purpose, any liability,
warranty or damage claims shall be rendered null and void.
If you require information on the use of the OBO isCon® system for some-
thing other than under the conditions of use described here, please speak
to your OBO contact.
1.5 Declaration of conformity
Lightning protection components are not subject to an EU directive.
Instead, OBO makes the manufacturer's declarations of conformity avail-
able for the appropriate components of the lightning protection systems.
These declarations of conformity certify the agreement with the named
standards and stored documents, but do not, however, contain any guar-
antee of properties.
You can find individual proofs for lightning protection components on the
OBO web pages (www.obo-bettermann.com).
1.6 Basic standards
Comply with the following standards*, amongst others, during the plan-
ning, mounting, maintenance and repair of lightning protection systems:
• DIN EN 62305-1 (IEC 62305-1, VDE 0185-305-1), Protection against
lightning Part 1: General principles
• DIN EN 62305-2 (IEC 62305-2, VDE 0185-305-2), Protection against
lightning Part 2: Risk management
• DIN EN 62305-3 (IEC 62305-3, VDE 0185-305-3), Protection against
lightning ‒ Part 3: Protection of structural facilities and persons
• DIN EN 62305-4 (IEC 62305-4, VDE 0185-305-4), Protection against
lightning ‒ Part 4: Electrical and electronic systems within structures
• DIN EN 62561-1 (IEC 62561-1, VDE 0185-561-1), Lightning protection
system components – Part 1: Requirements for connection compo-
nents
• DIN EN 62561-2 (IEC 62561-2, VDE 0185-561-2), Lightning protection
system components – Part 2: Requirements for conductors and earth
electrodes
• DIN EN 62561-4 (IEC 62561-4, VDE 0185-561-4), Lightning protection
system components – Part 4: Requirements for conductor fasteners
• DIN 18014, Foundation earthers
• IEC TS 62561-8 (draft)

General safety information
2 General safety information
Observe the following general safety information on handling the OBO
isCon® system:
• The work may only be carried out by lightning protection specialists,
who have been trained for the installation of standard-conformant
lightning protection systems.
• If there is a lightning strike, lethal currents can flow through the light-
ning protection system. Never work on the elements of the lightning
protection system during a thunderstorm or if there is a risk of one.
• Lethal voltages can occur during the handling of electrical resources.
Therefore, never work on parts through which power is flowing. Wear
suitable protective clothing and comply with all the required safety
guidelines!
• To install the OBO isCon® system, use only components of the OBO
product range, as otherwise there is no guarantee that safe installation
is possible.
• Only the jacketing of the grey OBO isCon® conductor may be painted a
different colour, as it does not possess any electrical properties which
could be at risk from paint.
• The production method means that metallic objects may have areas
with sharp edges. Wear suitable protective gloves to avoid cutting
injuries.
• When erecting function maintenance systems, take the necessary fire
protection regulations into account. These instructions do not mention
any fire protection standards which are to be complied with. Read the
OBO fire protection guide (article number: 9134859) for more informa-
tion.

Product description
3 Product description
3.1 Basic principles
Without any additional countermeasures, the high-voltage pulses which
occur when there is a direct lightning strike will cause arcing to insula-
tion surfaces. This effect is termed a creep flashover. When the so-called
creep discharge inception voltage has been exceeded, surface discharge
is initiated, which can bridge a gap of several metres. To avoid dangerous
arcing between conductive parts (electrical systems, pipelines, etc.), the
maintenance of the separation distance is a key requirement when plan-
ning and implementing a lightning protection system.
These days, the roof level of building complexes is used as an installation
area for air-conditioning, ventilation, transmission and energy collection
systems, meaning that the structural features may be in the way of the
required spacing between the air-termination systems and the electrical
installations.
The isCon® insulated lightning protection system is used to maintain the
required separation distance. Depending on the design, after the first
potential connection behind the connection element on the air-termination
rod, the isCon® conductor reflects an equivalent separation distance of
up to 0.45‒0.9 metres in the air or double that in solid matter. This means
that installation is possible directly on metallic and electrical structures. If
there is a direct lightning strike, the incoming energy is arrested through
the isCon® conductor to the building's earthing system. There is no direct
arcing between the down-conductor and the building to be protected.
The isCon® system has a tested arresting capacity of 150‒200 kA light-
ning surge current (10/350 μs). It primarily consists of the following com-
ponents:
– isCon® conductor
– Insulated air-termination rods
– System accessories for fastening (air-termination rod stand, support
and holder)
– System accessories for connection
3.2 isCon® conductor
According to DIN EN 62305-3/VDE 0185-305-3/IEC 62305-3, the insu-
lated isCon® conductor implements a separation distance of 0.45‒0.9
metres in the air and 0.9‒1.8 metres in the case of solid mater-
ials, depending on the product design. The isCon® conductor is equipped
with an external semi-conductive jacket, allowing it to limit high lightning
voltage pulses against a reference potential, by creating a connection be-
tween the external semi-conductive jacket and the building's equipotential
bonding, which is not energised with lightning current, in the area of the
connection element.
The isCon® conductor is flame-resistant according to DIN EN 60332-1-2,
weather-resistant and halogen-free. It is suitable for routing in external
areas and can be routed on roofs, in walls, in concrete, in facade installa-
tions or in buildings.
